Vehicle Display Control for Selective Overspeed Speed Alerts
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Drivers are bothered by constant display of vehicle speed information, leading to unnecessary visual clutter, and existing solutions fail to selectively hide this information when it's not needed, thereby missing opportunities for useful display.
Innovation Solution
A display controller that allows selection between an overspeed display mode and a non-display mode, forcibly switching to the overspeed display mode when the vehicle is in an overspeed state, using a difference between current and reference vehicle speeds for determination.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of information
If the information based on current vehicle speed is constantly displayed, then the driver can always access useful information, but unnecessary information enters the driver's field of view and causes bother
Solution Approach 1:
The display mode dynamically switches between display and non-display states based on real-time vehicle speed conditions. The system transitions from a static constant display mode to a dynamic mode where information is automatically hidden during normal operation and automatically shown when overspeed conditions are detected, making the display behavior adaptive to current driving situations
Solution Approach 2:
The system continuously monitors vehicle speed and uses this feedback to automatically control the display state. When the vehicle speed exceeds the reference speed, the feedback mechanism triggers automatic switching to the display mode, ensuring information becomes available precisely when the overspeed condition occurs without requiring manual driver intervention
2Object-affected harmful factors
If the driver can select not to display the information based on current vehicle speed, then visual clutter is reduced, but the information becomes unavailable even when useful
Solution Approach 1:
The system automatically detects overspeed conditions and self-activates the display function without requiring manual driver input. When vehicle speed exceeds the reference speed, the display controller autonomously switches from non-display mode to display mode, ensuring the information becomes available precisely when needed while maintaining driver preference for minimal display during normal operation
Solution Approach 2:
The system preemptively prevents the harmful effect of information loss by automatically counteracting the non-display state when overspeed conditions are detected. Before the driver would need the information, the system anticipates the need and automatically activates display, neutralizing the potential problem of information unavailability

AI summary
A display controller (100) that controls a display device (200) mounted on a vehicle including a display control unit (103) configured to control the display device (200) to display as selectable an overspeed display mode in which the display device (200) displays according to a difference between current vehicle speed and reference vehicle speed and an overspeed non-display mode in which the display device (200) does not display according to the difference between the current vehicle speed and the reference vehicle speed and control the display device (200) to forcibly display the overspeed display mode when the current vehicle speed is determined to be in an overspeed state.
